ERIS PA

                                  On Board Public Address System  

Share


The ERIS PA (ERmetrisIntegratedSystem) is a Public Address System for the on board railway market. Using Ethernet VOIP  - SIP protocol, power over ethernet and UIC568 to Ethernet gateway. The ERIS PA is  reliable, simple to configure and easy to maintain. Thanks to the redundant ermetris ethernet backbone solution we provide a fault tolerance solution with a unique audio quality.  
 


General solution technical overview

  • Supported VOIP protocols: MP3, G711, G.722, PCM Encoding, AACplus, MP3, Shoutcast/Icecast Source capability , Audio Level Supervision with SNMP Trap generation  IP Streaming via TCP, UDP, RTP, Multicast, IP stack with support for TCP/IP, UDP, RTP, SIP, DHCP, Multicast/IGMP

  •  High bandwidth for high quality audio

  •  Automatic adjustment for the audio through the noise sensors

  •  QoS priority setting thanks to the IP protocols
     

  •  Emergency Intercom are PoE  reducing maintenance and cables

  •  SNMP protocol for maintenance and failure notification

  •  High reliability and redundancy thank to the Ermetris Ethernet Backbone

  •  Compatibility with UIC 568 standard through a Ermetris gateway

                        


Power Over Ethernet

Extensive use of Power over Ethernet devices for less cable use and more reliable solution

Standard SIP protocol
